The 21st century began on January 1, 2001 and will end on December 31, 2100. It is the first century of the 3rd millennium. Late-20th-century quote from BIll Gates: "Another sign of a healthy, competitive industry is lower prices. The statistics show that the cost of computing has decreased ten million fold since 1971. That's the equivalent of getting a Boeing 747 for the price of a pizza."

At this stage of their evolving oral health, kids will be brushing both baby teeth and even some new teeth as their molars start to grow. Help them get the most out of their brushing routine with Oral-B Pro-Health Stages Monsters, Inc. power kids toothbrush. It’s an advanced children’s brush with the added benefits of battery power, featuring a rotating PowerHead that reaches, surrounds and cleans multiple surfaces, interdental tips for between teeth, and extra-soft bristles. Plus, the shape is perfect for small mouths, putting the power of a spooky good clean in their little hands.

I bought this for my three year old daughter and it works great. It is so much easier and faster to brush her teeth. There is also a fun factor which makes it exciting for her to use the brush. One nice thing is that when she or I pull it out of her mouth while brushing – it doesn’t move so fast that you get toothpaste spatter on everything. So if it comes out of her mouth and I don’t get it turned off right away, it doesn’t make a mess. Its great.

This is the 2nd electric toothbrush our 5 yr old has had. The first (crayola one) was great. Cute toothbrush, but the bristles would become rock hard and stiff. I’d have to try and soften them with my finger before he could brush with it. Which is gross to put your finger on. This would occur between his morning brushing and evening brushing. We’ve had it 2 months and finally threw it away after we bough another crayola one.

Somewhat of a battery eater, but its PERFECT for my son’s Monsters Inc fetish!He BEGS me to brush his teeth 5 times a day now, and besides all that excitement to brush his teeth, this toothbrush actually CLEANS well! He used to have this orangish tinge on his front two teeth that I couldn’t get to truly go away with a normal brush. After the first use with this one it was GONE! Just needed more power and circular motions to get it off I guess! Great buy!
